Turning Rubble To Reef

OPINION PIECE

The Mackay region is quickly becoming a premier fishing destination, offering 365 days a year fishing. Reef Catchments, as part of their “Turning Rubble to Reef in the Mackay Whitsundays” project, seeks to facilitate the expansion of coral reef habitat into otherwise bare areas of the marine environment. This will be achieved through the deployment of 30 Habitat Reef modules in the coastal waters off Mackay in the second half of this year.  

Installation of the Habitat Reef modules will have a positive flow-on benefit for recreational fishing. Habitat reefs are like natural reefs and will attract and provide fish habitat. The purpose-built Habitat Reef modules are structurally complex, providing habitat for fish, particularly during their vulnerable juvenile life stages. These modules are in addition to the ones in the Pioneer River which, after only six months, have shown through underwater footage that they are a huge success.  

The key design feature is a cave hollow at the bottom and a second, separated chamber above for small-bodied and juvenile fish species. By providing refuge from predation, this increases juvenile survival rates and boosts fish populations.  The outside surface of the Habitat Reef modules has been roughened to provide improved settlement areas for encrusting marine organisms such as coral polyps and oysters, expediting the growth of the structures.

The reef modules will be deployed across two sites easily accessible to anglers with small vessels. Species anglers can expect to encounter at the Habitat Reef sites include coral trout, grass emperor, striped bass, jewfish, golden snapper, small bait species such as hardyheads and herring, as well as mackerel and tuna.

They will be strategically positioned to transform areas of the marine environment into vertically complex reef ecosystems and will support the long-term sustainability of local fish stocks in the Mackay region. Our region is unique in that you can catch a fish within one hour in any direction, no matter what the time of year or weather conditions, and we need to make sure we have recreational fishing opportunities now and into the future.
